Since: Qt Location 5.0

Properties

Detailed Description

A place attribute stores an additional piece of information about a Place that is not otherwise exposed through the Place type. A PlaceAttribute is a textual piece of data, accessible through the text property, and a label. Both the text and label properties are intended to be displayed to the user. PlaceAttributes are stored in an ExtendedAttributes map with a unique key.

The following example shows how to display all attributes in a list:

import QtQuick 2.0
import QtPositioning 5.2
import QtLocation 5.3
ListView {
    model: place.extendedAttributes.keys()
    delegate: Text {
        text: "<b>" + place.extendedAttributes[modelData].label + ": </b>" +
              place.extendedAttributes[modelData].text
    }
}

The following example shows how to assign and modify an attribute:

//assign a new attribute to a place
var smokingAttrib = Qt.createQmlObject('import QtLocation 5.3; PlaceAttribute {}', place);
smokingAttrib.label = "Smoking Allowed"
smokingAttrib.text = "No"
place.extendedAttributes.smoking = smokingAttrib;
//modify an existing attribute
place.extendedAttributes.smoking.text = "Yes"
